              Today is 16 December 2011 and the A77 is nowhere to be found. The few that were sold all have mixed reviews. Even the positive reviews from the Sony website read with negative perspectives. NEX7 is the only Sony camera to be found in very few numbers. The A900 remains as the only good Sony camera that can actually be purchased. As such, it's markedly overpriced for a product that is three years old and out of production!
